Onix Radiant Tubing Onix Clamps Onix Fittings
Onix is an EPDM-based, aramid fiber reinforced tube with
an aluminum oxygen barrier. Its unmatched flexibility and
durability make Onix the best tubing for underfloor radiant,
cold weather installations, and snow melt.
Proven in tens of thousands of installations across North
America.
Onix is easy to install at any temperature, cutting
installation times by as much as 50%!
Onix does not expand or contract, and will never make any
noise.
Onix has excellent UV resistance.
Onix is not damaged by kinking.
Unlike PEX, Onix does not expand and contract and it
always stays in contact with the subfloor, making it ideal for
Underfloor applications.
Underfloor radiant lets builders construct a home the way
they normally do, without pouring concrete, double plating,
or other special considerations that can stop a radiant project
in its tracks.
With remodels on the rise, Onix is a great way to tap into this
growing market. You can easily snake Onix through floor
joists, around nails, piping, ducts and other obstacles you’re
sure to find in a remodel project.
Onix carries a 25-year warranty for residential and
commercial heating and snowmelting applications.

What is RadiantPERT
PE-RT Adhesive
EVOH Adhesive
PE-RT
PE-RT stands for Polyethylene
Raised Temperature. RadiantPERT is
manufactured with DowlexTM 2344, which
offers high strength, high temperature
resistance, and long life without crosslinking. PE-RT has been used successfully
for nearly 30 years in radiant heating
applications, and now commands about
25% market share in western Europe.
Non-Oxygen Barrier PEX Tubing
Non-barrier PEX — for heating and snow
now melting.

RadiantPEX/PERT
Unlike some PEX connection systems, our three choices for
RadiantPEX+ and RadiantPERT connections can be quickly made and
immediately pressure tested.
CinchClamps™ unique
stainless steel design allows
for easier connections in tight,
hard-to-reach spaces.
CrimpRings™ are precision-formed,
ductile copper connectors. When
crimped to brass crimp fittings, these
connectors form a permanent seal.
Fitting
SST-20 Compression fittings
do not require any special tools.
A simple crescent wrench is all
that is needed.

The RadiantPEX-AL Advantage
RadiantPEX-AL is a proven, long lasting composite
pipe engineered for radiant floor heating, snow
melting, and distribution piping.
Cross-linked polyethylene
RadiantPEX-AL installs faster than PEX because it
holds its shape, even with one installer.
RadiantPEX-AL has very little expansion/
contraction (about 1/8 that of PEX), so it's ideal
for "dry" applications or high temperature
distribution piping.
adhesive
Aluminum
RadiantPEX-AL retains its flexibility in cold
temperatures, so it can be easily installed in
winter weather.
RadiantPEX-AL Is Built to Last
RadiantPEX-AL pipe and fittings are manufactured
to meet or exceed ASTM requirements.

RadiantPEX-AL Compression Fittings
The RadiantPEX-AL compression fitting system from Watts Radiant is as simple
as it looks. All you need is a box-end wrench to tighten the nut. Made of solid
brass, these fittings are made for long, trouble-free service. Double O-rings and a
brass compression ring ensure a leak-proof connection. A polyethylene insulator
protects against corrosion between brass and aluminum pipe layers. Compression
fittings are listed by NSF to NSF-rfh.

R-flex
wattsradiant.com
800-276-2419
A long-lasting system
R-flex is a pre-insulated, flexible, energy-saving PEX
piping system with a durable, waterproof outer cover.
It consists of a long-lasting PEX carrier pipe or pipes
surrounded by thick insulation layers, all contained
in a unique double-wall outer casing for maximum
protection. The flexibility and light weight of R-flex
makes it far easier to install than rigid piping systems.
insulated piping systems
Insulated supply and return piping for:

•
Hydronic heating
Hydronic snow melting
District heating
Commercial and process piping
Geothermal
Agricultural piping
Biomass heat sources
Wood-fired boilers
Solar
• Cooling towers &
chilled water systems
Superior protection
Surrounding the inner PEX carrier pipe are several
layers of cross-linked polyethylene foam with a closed
cellular structure. This unique design provides R-flex
with a low water vapor absorption, enhanced R-value
insulation, and an excellent resistance to extreme
temperatures.
Most importantly, R-flex is able to maintain these
insulation properties over time. Other insulation types,
such as polyurethane (PUR) foam, can crush when
the pipe is bent, causing them to lose their insulative
properties.
Barrier PEX offers several advantages
• High resistance to corrosion and pressure
at high temperatures
• Exceptionally high abrasion resistance
• Superb chemical resistance
• Excellent longevity at high temperatures
Flexible, fast, and easy
R-flex derives a unique benefit from the use of the
polyethylene foam insulation and the double-wall
outer shell; increased flexibility. This feature provides
an advantage when running R-flex between buildings,
around trench corners, or through wall penetrations.
Simple to install
Traditional carrier pipes, such as copper or black iron,
require installers to cut and install transition fittings
to work around an obstacle. With R-flex, installers no
longer have to cut pipe and add connecting points.
R-flex bends around the obstacle.
Design it with RadiantWorks Professional®
RadiantWorks Professional allows designers to
properly determine the amount of R-flex required for a
project and an estimated amount of transitional heat
loss. Design it once. Design it right.

To calculate the total length of R-flex needed, add 5% to the straight-line distance
measured. This accounts for laying R-flex in a serpentine pattern. Also be sure to
account for the length of all bends. See the R-flex Design and Installation Manual for
more details.

project specifications. All trunks are made of copper; all fittings
and ball valves are brass. Every manifold is pressure tested before
leaving the factory.
Custom Tubular are sold in pairs. Manifolds are available in 1"–6"
ID trunk sizes.
Four configurations are possible:
Standard — no mini ball valves
BVR — mini ball valves on the return manifold
BVSR — mini ball valves on supply and return manifolds
BBSR — balance ball valves on return, mini-ball valves on
supply manifold

Stainless Steel Manifolds are sold in pairs, mounted to metal bracket as shown. Accessories such as Trunk Isolation Ball Valves, Vent/Purge Assemblies, and
Actuators are purchased separately. For added convenience, several of these accessories can be purchased in kits (see next page).
Each circuit can be individually balanced by adjusting the valve located under the blue cap. Maximum flow rates are 12 gpm for 1" manifolds and 22 gpm
for 1-1/2" manifolds. Individual circuit flow meters are 0–2 gpm for 1" and 0–4 gpm for 1-1/2" manifolds.
Manifolds and gauges are rated to 176°F at 87 psi pressure. Fittings are spaced at 2" on center. Order Onix, Crimp, or Compression
fittings separately.
Only SST20 styles are compatible with Stainless Steel manifolds.

Pressure Drop (ft. hd)
The IsoTherm is a compact, efficient pre-piped
and pre-wired pump and mixing valve control
designed to connect to Watts Radiant’s 1" Stainless
Steel Manifolds.
When combined with Watts Radiant’s
electrothermal actuators and actuator valve
controls (not included), a complete trouble-free
system is created, serving from 1 to 12 zones and
delivering up to 50,000 BTU/h (maximum of 68,000
BTU/h with a minimum boiler temperature of
160°F).
The mixing valve has a standard temperature
range of 113° to 140°F (45° to 60°C). The unit
is factory set at 131°F (55°C). The valve is easily
adjustable and locks in position with a “click-stop”
device, preventing temperature drift.
A three-speed 1/25-HP pump comes preinstalled and pre-wired, taking the guesswork
out of field installations. The Watts Radiant 1558
circulator will flow approximately 10 gpm at 10 ft.

Order manifold End Cap and/or Vent-and-Purge Assembly separately.
The Pressure Differential By-pass Valve for 1" Stainless Steel manifolds eliminates possible water velocity noise and
water hammer. With this valve, pumps cannot exceed the actuator close-off pressure. Pump life increases because of
minimal pressure surging as actuators open and close. Correct and constant flow is always ensured regardless of the
number of actuators open.
This Pressure Differential By-pass Valve installs directly on the 1" Stainless Steel manifolds. This valve adjusts from 0.7
psi (1.6 feet water) to 10.3 psi (23.8 feet water) using a graduated knob. Water by-pass capacity is 1.2 gpm to 9 gpm. The
knob is set and locked with a set screw to prevent tampering.

Custom Copper Tubular Manifold Pairs
Balancing Valve
Custom Copper Tubular manifolds allow you to specify exactly what
you want in a factory tested and warranted product.
Ball Valve
All Custom Tubular manifolds are supply and return pairs.
Use the model number diagram below to order custom manifolds.
Several accessories can be installed on your Custom Tubular Manifolds,
including (see page 46 for details):
• Brass O-ring Unions
• Full-port Brass Trunk Isolation Ball Valves
• Vent-and-Purge Assemblies
These must be treated as separate line items when ordering.
Ball valves with mini balancing valves are
useful for exact flow balancing. Balancing
is accomplished by rotating the threaded
spindle below the brass safety cap. Each turn
represents approximately 10% of full flow.

CustomCut™ Manifolds COST EFFECTIVE
CustomCut Manifolds are designed for flexibility at the wholesale and the installation level. They come in 4-ft.-long
copper “sticks" to be cut to length in the field — cut off five branches for a 5-branch manifold, seven branches for a
7-branch manifold, and so on. You can stock just a few types and have everything you need.
CustomCuts are made in various styles with:
• Brass fittings: Onix, PEX, and RadiantPEX-AL Compression.
• 1/2" and 3/4" Copper Stubs, for attaching standard ball valves or female copper sweat fittings in the field.
• 1/2" Brass Base Branches, for attaching Watts Radiant 1/2" male sweat fittings or Mini Ball Valves in the field.
CustomCuts are made with branches spaced at 3" (16 circuits) or 4" (12 circuits) on center, depending on the type of
manifold. They are available with and without Mini Ball Valves (MBVs).
CustomCuts are sold as a single manifold, not in pairs.

adjustment tools.
The jaws for the 15" tool are not interchangeable with the 19" tool. Also, the CrimpAll can only be used for fastening
crimp rings over crimp fittings and PEX/PERT tubing. Do not use it for press fittings or RadiantPEX-AL tubing as the
connection will leak.

Our Master Valve/Actuator Controls are intended to control Watts Radiant Electrothermal
Actuators, or any 24-VAC actuator or valve that draws 5 VA or less. The number of actuators
controlled depends on the separate 24-VAC external transformer (not included, order separately)
powering the system. An external 40-VA 24-VAC transformer can control 12 actuators maximum.
Up to 18 actuators maximum can be controlled with a 60-VA 24-VAC transformer. Order Slave
Valve/Actuator Controls separate for additional zones.
Master Controls are fused and include two end switches, each rated at 8A. Actuators are
switched by triacs, for quiet, safe, reliable electronic operation. Mounting is by DIN rail or surface
mount to a wall. The 60 VA transformer is surface mount.

Master Controls, they are intended to control Watts Radiant Electrothermal Actuators, or any 24-VAC actuator

Up to two additional 4-zone or 6-zone Slave Controls can be added to a Master Control. No
field wiring is required between — Masters and Slaves simply plug into each other (see below).
Each additional 40-VA 24-VAC transformer capacity can control an extra 12 actuators

using slab outdoor temperature reset to reduce operating energy costs. The 654 provides automatic start and stop
when used with the Snow / Ice Sensor 090. Automatic start with a timed stop is available when used with the Snow
Sensor 095. The 654 can operate a dedicated hydronic boiler or a mixing valve. Isolation relays are required to operate line voltage pumps. Electric systems require a separate GFCI and electrical relay contactor

Pressure Drop (ft. hd)
The IsoTherm is a compact, efficient pre-piped and
pre-wired pump and mixing valve control designed to
connect to Watts Radiant’s 1" Stainless Steel Manifolds.
When combined with Watts Radiant’s electrothermal
actuators and actuator valve controls (not included),
a complete trouble-free system is created, serving
from 1 to 12 zones and delivering up to 50,000 BTU/h
(maximum of 68,000 BTU/h with a minimum boiler
temperature of 160°F).
The mixing valve has a standard temperature
range of 113° to 140°F (45° to 60°C). The unit is factory
set at 131°F (55°C). The valve is easily adjustable and
locks in position with a “click-stop” device, preventing
temperature drift.
A three-speed 1/25-HP pump comes pre-installed
and pre-wired, taking the guesswork out of field
installations. The Watts Radiant 1558 circulator will flow
approximately 10 gpm at 10 ft. hd. This unit is ready —

The Pressure Differential By-pass Valve for 1" Stainless Steel manifolds eliminates possible water velocity noise and
water hammer. With this valve, pumps cannot exceed the actuator close-off pressure. Pump life increases because of
minimal pressure surging as actuators open and close. Correct and constant flow is always ensured regardless of the
number of actuators open.
This Pressure Differential By-pass Valve installs directly on the 1" Stainless Steel manifolds. This valve adjusts from 0.7
psi (1.6 feet water) to 10.3 psi (23.8 feet water) using a graduated knob. Water by-pass capacity is 1.2 gpm to 9 gpm. The
knob is set and locked with a set screw to prevent tampering.

Watts Radiant's Hydraulic Separator is designed to decouple the primary
loop flow from the secondary, impede particle and sediment movement
through a system, and to act as a point of air removal.
Flow through the hydraulic separator is dependent on the resulting
pressure differentials created by the circulators on either side. Circulators
should always be arranged in a counter-flow orientation.
Commonly used to simplify piping for condensing boilers, our separators
are constructed from type -L copper with a stainless steel screen and brass
air vent. A 3/4" brass drain, expansion tank tapping, and 5 temperature
gauge/sensor wells are standard. Rated to 210 ºF at 100 psi.

Condensing Boilers
These stand alone panels work with most condensing boilers. The Type 1 panel provides only a secondary circulator, and works
with condensing boilers that supply their own primary circulator. The Type 3 panel provides primary, secondary, and DHW
circulators. Both panels include a 1-1/4" primary loop with air remover and expansion tank connection (no tank) as well as optional
auto-fill assembly. All circulators are energy-saving 3 speed models, which enables the installer to adjust flows for optimal
temperature drops. The entire panel is enclosed in a powder coated steel enclosure for a professional, appliance style appearance.
The 1-1/2" stainless steel distribution manifold is equipped with thermal actuators on each circuit, and can supply up to 4 gpm
to each separate zone. Each zone has a balance valve and flow meter for precise flow balancing. A pressure differential bypass
eliminates velocity noise and helps extend the life of the system components.
Standard equipment includes:
• 1-1/4" copper primary and secondary piping, 1" copper DHW piping
• Primary, secondary, and DHW circulators, pre-wired and tested (Secondary circulator only on Type 1)
• High performance 1-1/4" micro-bubble air remover with expansion tank connection (tank not included) including a 10 ft
piece of 3/8" Onix for mounting tank outside of enclosure
• Isolation valves for easy servicing of circulators and easy air purging
• Spring check valves in primary loop and DHW piping
• 0-50 psi/60-320 ºF gauge
• 1-1/2" stainless manifold with thermal actuators, balance valves, flow meters and pressure differential bypass
• Zone actuator control, pre-wired and tested
• 9 ft 120V power cord
• Powder coated steel enclosure
• Optional Auto-fill assembly (Watts 9-11S M3 pressure reducing valve and backflow preventer)
Manifold adapters are required to transition to the distribution piping. PEX, PAP, copper or Onix can be used for distribution
from the panel to the radiant zones. Order manifold tube adapters separately.
The panel circulators are controlled by the boiler via field wiring. Outdoor reset, DHW priority and other features are
dependent on the boiler control.
Maximum flow rate is approximately 22 gpm. Each Watts Radiant 2699 circulator is capable of providing approximately 15
gpm at 20 ft hd on high speed.

Zone Panels (with or without actuators)
Zone panels with pre-wired actuators and
actuator control are our most popular panel. With
a professional appearance, multiple radiant tube
options and the wiring already done, it’s easy to
see why.
This Zone panel includes a 1" stainless steel
manifold housed in a powder-coated steel
enclosure with a latching door. The panel includes
manifold isolation valves with temperature gauges
and a vent/purge assembly. The enclosure is
designed to be recessed in the wall.
Maximum flow rate for entire manifold is 12 gpm.
Individual circuit flow meters are 0-2 gpm.
Panels with actuators may require an optional pressure differential by-pass valve (ordered separately).
If the by-pass valve is used, the maximum manifold
size in a box is reduced by 2 circuits, and the maximum manifold is an M-10.

GeoThermal Panel
These panels tie highly efficient water/water ground source heat pumps to a radiant system. This panel comes with
an outdoor reset control that adjusts the temperature of the buffer tank based on outdoor conditions. This allows the
heat pump to operate at the lowest possible water outlet temperature, ensuring maximum efficiency and extending
compressor life.
The hydronic system should be carefully designed, with consideration given to both the heat loss and floor coverings.
Most heat pumps can supply a maximum water temperature of approximately 115 ºF. This panel is designed for use
with a thermal buffer tank, a Primary panel, and a Distribution panel. The SG panel is typically connected to the inlet
side of any HydroNex Primary panel. Buffer tanks limit short-cycling of the compressor, maximizing compressor life.
The heat pump will only run when the temperature of the buffer tank falls below the outdoor reset control set point. If
there is no call for heat from the system, the solenoid valve will remain closed, directing hot water into the buffer tank
until the set point temperature is met. When the radiant system calls for heat, the solenoid valve will open, allowing
hot water to flow from the tank and/or heat pump.
• 1-1/4" copper primary and 1" secondary supply piping
• Energy-saving 3 speed Watts Radiant 2699 circulators, pre-wired and tested
• tekmar® 274 staging control (includes outdoor sensor)
• System solenoid to regulate flow through buffer tank or heat pump.
• Cat 5 cable electrical connection for fast and easy connection to Primary or Distribution Panels
Maximum flow rate is approximately 22 gpm. Each Watts Radiant 2699 circulator is capable of
providing approximately 15gpm at 20 ft hd on high speed.

TapeMats
Roll out mat and secure
to the floor.
Trowel thin-set and lay tile.
HeatWeave TapeMat Bathroom Layout
Bathroom Total Area = 80 sq. ft.
One Mat = 40 sq. ft. (2 ft. x 20 ft.)
HeatWeave TapeMat is the safest and easiest-to-install
heating mat in the industry. It is Listed by UL® for the U.S.
and Canada, and tested by Tile Council of North America for
all residential and moderate commercial applications.
All mats have the “S-pattern” wire construction and
produce 12 watts/sq. ft. HeatWeave TapeMat offers the
largest selection of mats in the industry with over 36 sizes
manufactured in two widths (2 ft. and 3 ft. wide) in lengths
covering up to 160 sq. ft. — with one mat! Just a few
benefits of HeatWeave TapeMats are:
1. Double sided tape strips speed up the installation
process by allowing either side of the mat to be "stuck" to the
floor.
2. TapeMats lay out flatter for easier troweling.
3. The industry’s first thin, open-weave construction
allows thin-set or self-leveling mortar to flow through the
mat and easily bond with the underlying material. This onestep application adds only 1/8” thickness over a normal tile
installation.
4. The industry’s first single power lead construction
makes mats easy to install and simpler to connect to the
control.
5. The industry’s highest-quality heating wire
using high-temperature insulation, tough outer jacket,
and oxygen-free copper heating elements for corrosion
resistance, temperature resistance, abrasion resistance,
and longevity.
6. The industry’s first twisted, twin-wire construction
creates ultra-low EMF (electromagnetic field).
7. 120- VAC and 240- VAC models available for small
residential to large commercial applications.
6. The industry’s only shielded and fully
grounded 10-ft. power lead provides safety and jobsite
durability. Power leads are color-coded for 120 VAC or
240 VAC.

HeatWeave
It’s easy to design a HeatWeave floor heating system.
For fast and easy sizing, go to www.wattsradiant.com for a Product Calculator
Evaluate how many square feet of floor are to be
heated. Do not put under cabinets or appliances.
Leave the mat at least 4” away from the toilet wax ring
and 4”–6” away from walls. Do install up to the toekick in front of kitchen or bath cabinets, and in front of
a toilet and/or shower and tub, so toes will stay warm.
Select one mat, or a combination of mats, to fill the
area. Remember, multiple mats of the same voltage
can be wired together to fill larger areas.

WarmWire Cable
WarmWire® is a simple, economical way to warm floors
and provide years of lasting comfort. It will warm all kinds
of floor coverings: ceramic & porcelain tile, stone, wood,
laminates, vinyl, or carpet.
Lay out and attach the CableStraps. Fasten the
WarmWire to the CableStraps as you weave it back and
forth across the floor. Put down a layer of thin-set mortar
and set your tile or stone. Install a layer of self-leveling
cement over the cables for hardwood, laminate, vinyl, or
carpeted floors. Our installation manual and DVD shows all
the details.
Kitchen/Breakfast Layout
Due to differences in heat loss between the kitchen and
breakfast areas, two different spacings were used: 3” on center in the kitchen, and 2” on center in the breakfast area due
to the higher heat loss.
Spool termination
WarmWire is now UL listed for
installation in shower floors and
benches! See manual for details.

WarmWire Spools
• Evaluate how many square feet
of floor to be heated. Do not
put under cabinets or appliances.
Generally, about 85–90% of the
open areas should be heated.
Leave the wire at least 6” away
from the toilet wax ring and 4”–6”
away from your walls. To keep
toes warm, install right up to the
toe-kick in front of kitchen or
bath cabinets, and in front of a
toilet, shower, or tub.
How much WarmWire should I
order?
1. Calculate total wall-to-wall
area of the room. Subtract the
square footage of all built-ins (tub,
toilet, cabinets, etc.).
(Total area – built-ins) = ( ____ –
____ ) = ____ sq. ft.
2. Multiply this area by 0.90.
Round down to the nearest
5 sq. ft. This is the heated area.
______ x 0.90 = ______ sq. ft. of
heated area.
3. Select the appropriate cable(s)
based on the square footage
of heated area and the “spacing
factor”
4. Choose a “spacing factor” of
2”, 2.5”, or 3” on center. Below
are guidelines for application and
spacing recommendations.
• 2” on center = 15 Watts/sq. ft.
Use on concrete basement slabs,

UnderFloor Mats
UnderFloor mats are the perfect solution for nearly
every type of floor covering. These special mats warm
existing floors without having to replace the floor coverings. If you have access under a floor, simply staple
UnderFloor mats between the joists.
These effective, UL-Listed mats deliver 10 watts/sq. ft.
of floor area (about 34 BTU/hr/sq. ft.).
UnderFloor mats will warm wood, vinyl, laminates, or
o coverings.

will
warm up as much as other floor coverings due to
the high insulation value of carpet and padding. You
may experience a temperature rise in the floor of only
6°–10°F, which may or may not meet your satisfaction.
Insulation installed below the mats is essential to complete the installation.
Consider these benefits of UnderFloor mats:
1. Easy staple-up installation between floor joists.
2. Manufactured in nearly 20 different lengths in
12” and 16” widths. Mats of any size (same
voltage) may be combined to heat any type of room.
3. 120-VAC and 240-VAC models for small to large
projects.
4. Highest-quality heating wire using ETFE hightemperature insulation, and oxygen-free copper
alloys for corrosion-resistance, temperature-resistance, abrasion-resistance, and longevity.
5. Shielded and fully grounded 10-ft. power lead for
safety and jobsite durability (longer lengths available
on request). Power leads are color-coded for
120 VAC and for 240 VAC.
Do not install UnderFloor mats in mortar
or cement, or install them in the same control
zone as HeatWeave mats or WarmWire cables.
These products have different heat output, and
are manufactured for different applications.

Sample Kitchen Layout
Using UnderFloor Mats
Each UnderFloor mat is designed to be
installed in only one joist bay. The mats cannot
be cut shorter to fit a shorter joist bay or
modified in any way to fill multiple joist bays.
However, more than one mat may be installed
in a joist bay where there are barriers such as
cross bracing or blocking.
In this kitchen layout, four 9.5’ x 16” and
eight 4’ x 16” mats are required to warm the
floor area. The mats are wired together in
parallel (not in series) at junction boxes below
the floor, then electrical wire is fed over to the
SunStat control.
Select mats for the easiest wiring possible.
If all the power leads end up at one end of
the room, it will be much easier to wire them
together in the junction boxes. Junction boxes
must be accessible after all finishing work is
completed.

How much SlabHeat should I order?
1. Calculate total wall-to-wall area of the room.
Subtract the square footage of all built-ins (tub, toilet,
cabinets, etc.).
(Total area – built-ins) = ( ____ – ____ ) = ____ sq. ft.
2. Multiply this area by 0.90. This is the heated area.
______ x 0.90 = ______ sq. ft. of heated area.
3. Select the appropriate cable(s) based on the
square footage of heated area, from the tables.
Select the cable(s) whose total sq. ft. coverage comes
closest to, but does not exceed the heated area.
4. Remember that a SunStat will handle up to 15 amps.
Multiple cables will generally require a Relay or another
SunStat control.
Call us if you need help sizing a system.

SunStat® Relay II
If a mat or cable system requires more than 15 amps, we recommend installing SunStat Relay IIs. Relay IIs
connect directly to SunStat Pro II or View thermostats for simple, elegant control of larger systems. Relay IIs are
dual voltage (120 VAC or 240 VAC), have a 15-amp capacity, an on/off switch, a GFCI and heating indicator.
It’s possible to control over 1500 sq.ft. of electric floor warming using 120 VAC and over 3,000 sq.ft. using 240
VAC floor warming mats or cables. First, find the amp draw for each HeatWeave product in the project. Then
determine how many mats or cables can connect to each relay. Up to ten 15-amp Relay IIs can connect to one
SunStat. Ten Relay IIs, plus the internal relay in the SunStat, provide a total capacity of 165 amps! Each Relay II
should be connected to individual 20-amp maximum breakers, as shown below.

Most instances of damage to the heating wire occur when a metal trowel is banged onto the floor to
remove excess mortar. A metal trowel can cut like a knife and either damage or totally sever the wire. The
CableTrowel simply cannot damage the wire. With rounded notches that are 3/8" wide by 1/2" deep, it is
perfect for applying thin-set mortar over WarmWire or HeatWeave Mats.

ProMelt™
ProMelt Mats melt snow and install quickly.
All you need for a typical small-to-medium size
project is a control and mat.
ProMelt heating elements are surrounded
with high-temperature ETFE insulation and the
engineered polyurethane outer jacket tolerates
300º F asphalt and the machines that roll
it in place.
Each mat holds dual heating elements on 3
inch centers on a reinforced tape grid. There’s
a grounded power lead on one end for a fast,
single-point electrical connection.
Mats come in two energy outputs:
•120VAC mats are 38 Watts/Sq. Ft.
•208, 240, & 277 VAC mats are 50 Watts/Sq. Ft.
ProMelt has more sizes and more options
than any electric snow melting system. Standard
size widths are 2 feet and 3 feet. You can order
mats to cover from 9 to 112 square feet. Our
catalog lists 60 standard sizes. Call us if your job
requires custom sizes.

buildings to reduce injury, liability and

zoned and operated with automatic controls.
Follow these recommendations when selecting
ProMelt Mats:
1. Determine what voltage will be used:
120V, 208V, 240V, or 277V.
2. Determine the heat output.
The climate and amount of snowfall will dictate this choice. In
general, most systems will require 50 Watts/Sq.Ft. to melt snow
and ice. Some residential or light commercial systems in temperate climates, may need only 38 Watts/Sq.Ft. spacing.
3. Determine the square footage of the area to be melted.
Do not include areas under built-ins like planters or similar
obstructions. Stay 3-6” from edges of slabs and do not cross
expansion joints if possible. Add up all the areas to be melted
and round down the nearest mat size(s) to fill the area. Either
2’-wide or 3’-wide mats can be selected.
Alternatively, you might want to figure the total length of
mat needed. This can be better for an area such as tire tracks,
sidewalks or stairways. As an example, a sidewalk is 30” wide, 25’
long, and has a 240V power supply. The best choice would be a
2’ x 24’ mat, 240V mat.
More than one mat can be used to melt an area(s). Combine
mats in a manner not to exceed the capacity of the electrical
control selected. If using our ContactorPro controls, each area
should not exceed 50-amps, since these controls are built with
50-amp contactors. Therefore, we recommend dividing the area(s)
into “sub-zones”, if necessary or desired, to minimize the mat amp
load connected to each contactor.

ProMelt™
ProMelt Cable offers versatility
for odd shaped areas or
last minute design
changes.
ProMelt Cables cost less than ProMelt Mats and give
you more layout options.
In both products, the heating elements are
surrounded with the same high-temperature ETFE and
engineered polyurethane outer jacket for long life and
jobsite toughness, including installation in asphalt.
ProMelt Cables are usually tied to reinforcing wire
3 or 4 inches on center. That provides either 50 or 38
Watts per square foot. ProMelt Cable can go perimeter
to perimeter or fill odd-shaped areas for complete snow
melting coverage.
There are a lot of ProMelt Cable sizes in stock in four
single-phase voltage options. All the cables terminate
at one end with a power lead so you only make one
connection to your electrical source.
ProMelt Cables save on material costs, give you
more flexibility and carry a 10-year limited warranty.
With ProMelt Cable, odd
shaped areas can easily be
snow melted. Some of these
include porches, steps,
driveways, and sidewalks.

Alternatively, you might want to
figure the total length of cable needed.
This can be better for an area such as tire
track melting. As an example, a 24”-wide
track with 3” o.c. ProMelt Cable will go
back and forth eight times to fill a 24”-wide
track. If the tire track is 25’ long, then each
track will need 8 lengths x 25 feet or a total
of 200 feet of cable.
More than one cable can be used
to melt an area. Combine cables in a
manner not to exceed the capacity of the
electrical control selected. If using our
ProMelt ContactorPro controls, each area
should not exceed 50-amps, since these
controls are built with 50-amp contactors.
Therefore, we recommend dividing the
area(s) into “sub-zones”, if necessary or
desired, to minimize the cable amp load
connected to each contactor.

Follow these recommendations
when selecting ProMelt Cables:
1. Determine what voltage will be used:
120V, 208V, 240V, or 277V.
2. Determine the heat output.
The climate and amount of snowfall
will dictate this choice. In general, most
systems will require 50 Watts/Sq.Ft.
spacing (3” o.c.) to melt snow and ice.
Some residential or light commercial
systems in temperate climates, may
need only 38 Watts/Sq.Ft. spacing
(4” o.c.).

PM-2B
ProMelt Snow Sensor Controls: Pole-mount, 120/208/240V
P
The
T PM-2B sensor control is used to detect snowfall and low temperature to activate the ProMelt
Mats or Cables. It is a “pole-mounted” control with a “fixed” moisture sensor mounted to the top.
M
TThe PM-2B offers automatic activation, rain/snow detection, adjustable trigger temperature, and a
drying cycle, as well as “manual on” operation. It operates on line voltage (120/208/240V,
d
not 277V) and has a 30 Amp capacity. It is a stand-alone control intended for relatively
n
ssmall systems (up to 30 Amps). It should not be used with our ContactorPro series of
PM-DP
ProMelt controls, as those are designed for 24V control sensors. The unit measures
P
aapproximately 5” x 7” x 3”.
A recommended upgrade to the PM-2B is our PM-DP Control Panel. This control allows
cconvenient indoor monitoring and control of the system for manual on, automatic, and
sstandby operation. It communicates with the PM-2B through a simple low-voltage cable.

ProMelt Snow Sensor Controls: Pole-mount, 24V
The PM-224 and PM-824 are used to detect snowfall and low temperature to
activate the ProMelt Mats or Cables. The PM-224 has a moisture sensor “fixed” to the
top. The PM-824 has a remote moisture sensor, which allows mounting the control
in a more convenient location. It can be mounted on a wall or inside the building
and the sensor outside exposed to the snowfall, adding convenience of operation
and adjustment. Both models offer automatic activation, rain/snow
detection, adjustable trigger temperature, and a drying cycle, as
well as “manual on” operation. Either control will operate in
conjunction with our Contactor Pro series of ProMelt controls,
which should be ordered separately
(see next page). The unit measures approximately 5” x 7” x 3”.

ProMelt ContactorPro™
The Contactor Pro panels are complete “turn-key” solutions for activating larger systems of ProMelt Mats and Cables when used in
combination with a PM-224 or PM-824 snow detector. They’re available in three panel sizes: 50 Amps, 100 Amps, and 200 Amps. An
additional 200-amp extension panel allows coverage for even larger systems. 120V, 208V, 240V, or 270V is supplied to the panel and a 24V
Class 2 transformer allows connection to the snow detector.
Each Contactor Pro panel is complete with “system on” indicator light, manual
override by a 4-hr timer, simple 24V wire terminal connections to the snow detector,
and outputs for connection to an extension panel. The CP-50 has one 50-amp
contactor, the CP-100 has two 50-amp contactors, and the CP-200 has four 50-amp
contactors. Systems should be designed to connect one or more ProMelt Cables or
Mats in combinations not to exceed the capacity of individual 50-amp contactors.
Each panel is NEMA Type 1 for mounting indoors on a wall, has knockouts for conduit,
and measures 12” x 12” x 4”.
